[0002] Insulators are a special type of insulating control that plays an important role in overhead transmission lines. In the early years, insulators were mostly used on telegraph poles, and gradually developed into high-voltage power lines. Many disc-shaped insulators are hung on one end of the tower to increase the creepage distance. They are usually made of glass or ceramic.

However, when assembling multiple insulator bodies, the operator needs to rotate the connecting column one by one to connect the multiple insulator bodies. The operation process is cumbersome and it is not convenient to quickly assemble or disassemble the multiple insulator bodies, which reduces the work efficiency of the operator.
